AIHA Awareness Day is observed worldwide every March 25 to highlight autoimmune hemolytic anemia (AIHA) and other acquired hemolytic anemias. This day brings together patients, caregivers, families, physicians, researchers, and other stakeholders to advocate for improved patient care and funding for research. AIHA is characterized by the immune system producing antibodies against the body’s own red blood cells, leading to serious health complications. The day aims to celebrate the resilience of those living with this rare disease, educate the public, and promote research initiatives. Participants are encouraged to engage on social media using the hashtag #AIHAAwarenessDay and to support organizations that assist patients with AIHA.
